Thanks buddy for the response.
Yes i have set the switch to full speed o nseveral ocassions but to no avail
I have now cut off the switch, but now its on @ 900 rpm and still cant change speed with the akasa pro fan controller.

How come antec fans dont work with my akasa pro fan controller?

WOudl it be wise to get an antec 900 2 case, remove the fans and replace them with similar size and colour akasa fans?
